To all whom it may concern Be it known that I, RICHARD L. DEZEN- pour, acitizen of the United States, residing at Richmond Hill, county ofQueen's, State of New York, have invented certain new and usefulImprovements in Gas-Meters, of which the following full, clear, and eX-act description.

My invention relates to in'iprovements in gas meters, and has for itsobject to provide a simple and sensitive indicator operating inconnection with one of the lower flag-arms of the meter, whereby whenthe meter mechanism is moving at even a slow rate, such movement will beclearly indicated.

It further has for its object to provide an inexpensive and efli 'cientindicator in which the speed of the indicator during all periods issuiii'ciently rapid to be clearly perceptible.

The following a description of an embodiment of my invention, reference,being had to the accompanying drawings, in whi'cha I Figure 1 shows aplan View of a meter embodying one form of my invention, with the coverremoved. Fig. 2 is a front elevation of the upper portion of said meter.Fig. 3 shows a transverse section of Fig. l on the line Fig. l shows inperspective a modified embodiment of my invention. Fig. 5 shows a planview of a modification with the cover'reinoveda- Fig. 6 is a frontelevation of the same with a portion of th'e case broken away. Fig;shows the same front elevation with a peep-hole throiigh the easing forobserving" the ,indicater. Fig. 8 shows a transi erse section of themeter casing through the peep-holeand a portion of the indicator in sideelevation. Fig. 9 shows a detail of the indicator of Fig. 5.. Fig.- 10shows a modification of that particular form.

ings, 1 is the meter casing having an inlet 2.

3 is a crank shaft to which the lower flag arms H are connected throughthe tangent post 5.

6 is one of the upper flag arms connected to the flag wire 7 in theordinary manner.

The use of the terms upper and lower in reference to the portions of theflag arms follows the ordinary use of those terms in connection with thetwo portions of the human arm.

8 is the ordinary indicator train driven by the spur Wheel 9 upon theshaft 10.4

. a For the purposeof indicating small movements of the mechanism byineansembodymg my invent on, Tprovude {an indicator connected to oneofthe lower flag arms 1n a suitable manner. In the preferred form, thisindicator is a slide 23 located in front or the dial 2d of the ordinaryregistering device. Thisslide 28 is operated by a lever 25, hichisfulcrumed in a lug .36 secured to the meter casing'l, the rear end ofthe lever 25 being engaged by the upturned flange of a plate 27 securedto the lower flag arm 4 passing througl'i a hole in said flange.

As gas passes through the meter, the flag wires and flag arms move tooperate the crankshaft in the ordinary manner. When the upper flag ar'm6audits flag wire 7 reach either end of their movements, they pause for aconsiderable period. j During this pause, the lower flag arm 4k ismoving at a rapid rate about its axis formed by the outer end of thefiag'arm 6, with the result that the plate moves the lever 25 so as tocause the indicator 23 to move at a comparatively rapid rate duringsubstantially all the that the meter is infoperatiom the rapid movementbeing due in part to theloiigitudinalinoveinent ofthe 'lowerl arm 4caused by the rapidoscillation'of the iip pierand part of the time tothe comparatively rapid movement of the lower arm 4 about the aXisformed by the free end of the upper arm 6. 'l/Vith'thi-sarrangementlthefevers als oftlie'moveinents of the indicator 23 aresubstantially instantaneous, sorthat the indicator is moving at arelatively rapid rate during substantially the whole period of operatioii bf thefmeter. Substantially" the same result can bj btain'ed byriiountingthe indicator upon anariii which is fulcrumed at he. ba Qfthemet r, andi h ch isa fiur ated by'a yoke dependingfrom the lower flagarm 4. This arrangement is shown in Fig. 4, in which 18 is theindicatorand 19 is the lever carrying the same having its lower endsurrounding the rear flag arm 7". This lever is not attached to the rearflag Wire,

but is free to move thereon, being supported T by a collar 7 Which issecured to said flag Wire. Projecting from the lower flag arm 4: is ayoke 20 having an upturned end 2 1, within which the lever 19 lies. Thisyoke projects well toward the front of the meter. As the meter operates,the fi. arm 4 moves so as to move the lever 19 witii the indicator 3.8at a rapid rate during substantially all the period of operation of themeter, the

yoke 20 sliding upon the arm 19 to permit" such movements The. indicatoris visible through a peep-hole22 Another form of indicator actuated'bythe lower flag arm 4 is shown in Figs. 5, '6, 7 and 8. In this form 11is the indicator rigidly connected in any suitable manner to the lowerarms. This indicator has a portion extending in a forward directionsubstantially at right angles to the lower arm ac-and carrving asegmental graduated'portion 11. This graduatedportion rests on a support12 carried bythe upper arm 6 so as to relieve the lower arm 4 of anystrain; At the top of the meter, I provide a peephole consisting of thebushing 13 having a movable cover .14. The inner end of this bushing isprovidedwith-a recess which forms a seat for the glass13,which is heldin position by a gasket 15 and a holding ring 16, the latter being heldin place bv anv suitable ,rneans, as for instance, by solder. Thebushing 13 is soldered in an opening in the meter top, the solder beingapplied'on the inside, as at17. so that the bushing cannot be tamperedwithout detection.

14 is a marker to assist in reading the indicator 11 As gas passesthrough the metertfrom the inlet 2 to the outlet 2', the segmentalportion 11' is keptingmotion at a rapid rate during substantially allthe time that the meter is in operation. The segmental portion canbeattached to the lower side of-the flag arm 4, as indicated in .Fig.

1.0,in whichcase, however, apeep-hole such as 22 shown in Fig. 4, isprovided in the front wall of the meter casing. V

, As willbe evident to those skilled in the art, the; apparatus permitsof various other modifications without departing from the spirit of Vmvinvention or the scope of the appended claims. a c 7 VVhatI claim is: i

3 111. In a meter, a combination of the meter mechanism including frontand yrear flag wires, two upper and two lower flag arms and a crankshaftoperated thereby, of an Copies cithis patent may be obtained for in thefront wall of themeter.
